Abstract
The invention relates to a method for preparing architectural ceramic bricks by wet-casting molding of granite waste wet. The method comprises the following steps: by taking granite wastes as main raw materials, by taking water as a dispersing medium, by taking carrageenan, sesbania glue and low polymer sodium polyacrylate as additives, mixing to obtain slurry; preparing architectural ceramic bricks by adopting a wet-casting molding process, drying and fettling, firing at the temperature of 1140-1180 DEG C, and cooling to obtain the architectural ceramic bricks with the breaking strength of 50-70MPa. The method is simple in preparation process; compared with the traditional architectural ceramic dry pressing process at present, the method has the advantages that large tonnage press and spray material preparation are saved, dust and noise pollution are reduced, the production cost is low, hard brittle materials serve as main raw materials, the problem that clay and other traditional high-quality ceramic raw materials are increasingly scarce is relieved, and the problem that a green ceramic body molded by using the hard brittle materials is low in strength is solved. Moreover, compared with similar architectural ceramics, the architectural ceramic bricks are low in price, and higher economic benefits can be brought.
Description
Technical field
The invention belongs to architectural pottery field, be specifically related to a kind of method of preparing building ceramic tiles with granite waste material wet method casting.
Background technology
Along with national economy constantly develops, the continuous propelling of novel urbanization, the scale of future architecture ceramic industry will further expand, architectural pottery is as high resource consumption, high energy consumption industry, very large to the demand of raw material, and the allowable exploitation of traditional high-quality ceramic raw material clay is fewer and feweri, shortage of resources problem is day by day serious.
China is in the world main granite resource big country and big producing country, according to < < 96 Mineral Resources in China report > > incomplete statistics, Granites In China Mineral resources total amount is about 230 ~ 24,000,000,000 cubes of square meters, and the reserves of verifying at present only account for 4% of total resources.Al during grouan chemistry forms
2o
3and SiO
2content up to 86%, can replace traditional raw material to prepare architectural pottery.Yet in order to guarantee the processability of base substrate and to have certain green strength, in blank formulation, the content of lean property powder is restricted.
The chemical constitution of table 1 granite waste material
Chemical constitution | SiO 2 | Al 2O 3 | Fe 2O 3 | TiO 2 | CaO | MgO | Na 2O | K 2O | Burn and lose |
Grouan | 71.76 | 14.02 | 2.68 | 0.40 | 2.38 | 0.46 | 3.21 | 3.77 | 1.32 |
At present, architectural pottery generally adopts mist projection granulating dry powder compression moulding technique in producing, this kind of moulding process not only can produce a large amount of dust hazard HUMAN HEALTH in process of production, and the spray tower using, great tonnage press equipment cost are high, energy consumption is large, is the major cause of architectural pottery production high energy consumption.
Therefore, be in the architectural pottery a large amount of lean property of the grouan waste materials that utilize, reduce the consumption of Building Ceramics Industry resource and the energy, need new moulding process.Macromolecule polysaccharide wet method casting is the novel forming technology growing up on gel casting forming basis, and gel casting forming is mainly used in special cermacis field at present, and the carbohydrate using is starch, agarose, gelatin, sodium alginate.Utilize carrageenin, sesbania gum to there is no report as the wet method casting in jelling agent architectural pottery field.
?
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method of preparing architectural pottery with full poor material wet method casting.
For solving above technical problem, technical scheme of the present invention is: a kind of method of preparing building ceramic tiles with granite waste material wet method casting, it is characterized in that: employing granite waste material is main raw material, water is dispersion medium, additional carrageenin, sesbania gum, low-molecular polypropylene acid sodium are that additive is mixed to get slurry, then adopt wet method pouring forming technology to make building ceramic tiles base substrate, after drying, repaired biscuit, at 1140~1180 ℃, fire, obtain the building ceramic tiles that folding strength is 50~70MPa after cooling.
Described body drying temperature is 50~80 ℃, and be 40~80min time of drying.
Intensity after described body drying is that 1~2MPa, green density are 1.1~2g/cm
3.
The preparation process of described slurry is: carrageenin and sesbania gum are dissolved in by a certain percentage and in water, are configured to pre-mixing liquor, granite waste material and water, low-molecular polypropylene acid sodium are prepared burden by a certain percentage, then pre-mixing liquor is added wherein, and more than 60~80 ℃ of heated and stirred 60min.
The weight percent of described slurry consists of: granite waste material 50~60wt%, water 40~50wt%, additional carrageenin 0.4 ~ 1.5wt%, sesbania gum 0.1~0.4wt%, low-molecular polypropylene acid sodium 0.5~2wt%.
The granularity of above-mentioned granite waste material was 200 mesh sieves.
Traditional architectural pottery preparation technology will adopt spray tower powder process at present, adopt great tonnage press dry-pressing formed, and its preparation process dust is large, and noise is strong.The present invention adopts wet method casting to prepare ceramic construction pottery, this kind of technique not only can be avoided the great tonnage press in traditional architecture ceramic dry-pressed production process, the powerful devices such as spray tower, and utilize this kind of technique to prepare architectural pottery and can effectively reduce dust in production process, the pollution of noise etc., it is main raw material that the present invention simultaneously adopts granite waste material, not only alleviated the worsening shortages problem of traditional high-quality ceramic raw materials such as clay, and to compare price lower with similar architectural pottery, can bring higher economic benefit, therefore there are wide market outlook.
Accompanying drawing explanation
Fig. 1 is to be process flow sheet of the present invention.
